That's a Goat Head Thorn.
Joey: "Dude, i have like a hundred thorns in my front tire. Sweet!"
Joy: "um, so do i"
Matt: yelling back at us, "do one of you have a flat?"
Joy/Joey: "yes, we both do"
As we had a pit contest to see who would fix it first, Matt's back tire went flat. Since i finished first...I soon realized my front was flat as well. When i went up to Joey's bike, i saw his front was flat too. Then it was all quiet and what not, and we could hear the air coming out of Matt's front tire too.
6 flats total. No tubeless. 3 tubes.
As we were walking our bikes up a really rude asphalt climb, i asked Matt how his day was. He said "way better than last weekend." Yes, this is true. Every ride will be better than last weekend!
